IMPROVEMENT IN WATCH-WlNDING DEVICES.

Specification forming part of Letters Patent No. 216,814, dated June 24, 1879; application filed June 28, 1 78.

To all whom it may concern:

Be it known that I, BENJAMIN WORMELLE, of Brighton, in the county of Suifolk and State of Massachusetts, have invented an Improved Watch-Winding Device, of which the following is a specification.

My invention relates to that class of watch winding devices which are designed to be applied to watches already manufactured or in use, and which are made detachable, so as to admit of their being used also for setting the hands.

The object of the invention is to produce a device which shall be strong and durable, easily applied, and economical in construction, and which shall obviate the necessity of the cutting out of the cap of the watch in apply- 111g.

Referring to the drawings, Figure 1 represents my invention, on an enlarged scale, in elevation. Fig. 2 is a side view of the same. Fig. 3 is a top view of the pipe, showing the shoulder and central square openin Fig. 4 is the circular sprin Figs. 5 to 13 represent modifications of details of my invention.

a in the several figures represents the pipe of the watch-winder, provided with a square opening through the center longitudinally, and fitting the square of the watch-arbor. The upper portion of the pipe a is formed with a shoulder, d, extending entirely around, and a projecting head, I), to opposite sides of which is attached, by means of a pin, k, the thumbpiece g. Upon the shoulder 07, and surrounding the projecting portion b, is fitted a circular spring, 0, consisting of a thin strip of metal.

The shoulder (1, instead of being level all around, is curved downward on opposite sides below the points of connection of the thumbpiece g with the pipe a, so as to allow the spring 0 to yield to the pressure of the hinged edges of the thumb-piece as the latter is turned up or down, and also to hold the thumb-piece in position when opened or closed, which resuit is effected by the spring hearing against the square ends of the jointed portion of the thumb-piece,

The thumb-piece y, it will be seen, can he turned down at either side of the pipe.

The shoulder (I may pass entirely around the pipe or only partially around; but in any case a socket or recess should be left for the attachment of the thumb-piece in such a manner that it will not interfere with the cap of the watch.

Fig. 7 represents a pipe in which the spring passes only half-way around, the ends being fitted in sockets I, one on each side, and to which is adapted the thumb-piece g. The spring may also be arranged in sections around the pipe, the ends of the same bearin g against the hinged portion of the thumbpiece with sufficient force to hold the latter in an open or a closed position.

The thumb-piece may be hinged to the pipe by boring holes in both pipe and thumb-piece and inserting pins therein, or it may be at tached to the same by means of trunnionsff, forming a part of the pipe, as shown in Fig. 5; or projections f f may be formed on the inner ends of the thumb-piece, as shown in Fig. 11, and fitting in corresponding holes in the pipe. In either case the thumb-piece is to be sprung on, which is effected by means of the slits h h (one or more) in the thumb-piece, as seen in Fig. 11.

When trunnions are used a semicircular spring may be applied to the pipe, or a cut eir cular spring may be used.

In Fig. 6 are shown two lips, i i, projecting from the pipe (1. near its upper portion, for sup porting the spring 0, instead of the shoulder (I, as in Figs. 1 and 2.

Fig. 8 shows a form of spring adapted to a pipe having a flange extending partially around the pipe, made as described in Patent N o. 2043M, already granted to me, the spring on the pipe opposite the flange resting on a lip under the flange of the thumb-piece.

Fig. 13 represents the spring resting in a socket upon the top of the pipe with a flange extending wholly around the pipe.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-
